If you've got the $$$$s, use hardware for sure... If its a small company (or
$$$s are an issue) and the server wont be hit all that much, IDE software
raid will be fine. 18G is SMALL :)

Never having used software raid on a *nix before, is it really as good as
hardware? I know on the other platform we use here, s/w raid runs like a
dogs breakfast. I would really like to put *big* SCSI drives in (at least
18Gb, I suppose that's not big today tho') to cope with expansion. I am
trying to move away from IDE.

Would you still recommend s/w implementation even with SCSI?
